简要总结

This 2-arm, randomized, open-label study will evaluate the efficacy and safety of trastuzumab emtansine versus trastuzumab as adjuvant therapy in patients with HER2-positive breast cancer who have residual tumor present in the breast or axillary lymph nodes following preoperative therapy. Eligible patients will be randomized to receive either trastuzumab emtansine 3.6 mg/kg or trastuzumab 6 mg/kg intravenously every 3 weeks for 14 cycles. Radiotherapy and/or hormone therapy will be given in addition if indicated.

结局指标

主要结局

Invasive Disease-free Survival (IDFS) Rate at 3 Years

时间窗: At Year 3

IDFS event was defined as the first occurrence of any one of the following events: ipsilateral invasive breast tumor recurrence (i.e., an invasive breast cancer involving the same breast parenchyma as the original primary lesion); ipsilateral local-regional invasive breast cancer recurrence (i.e., an invasive breast cancer in the axilla, regional lymph nodes, chest wall and/or skin of the ipsilateral breast); distant recurrence (i.e., evidence of breast cancer in any anatomic site-other than the 2 above-mentioned sites - that has either been histologically confirmed or clinically diagnosed as recurrent invasive breast cancer); contralateral invasive breast cancer; death attributable to any cause including breast cancer, non-breast cancer or unknown cause . 3-year IDFS rate in ITT population was estimated using Kaplan Meier (KM) method and the percentage of participants who were event-free 3 years after randomization was estimated.

Kadcyla Shows Sustained Survival Benefit in HER2-Positive Early Breast Cancer• Long-term analysis of the KATHERINE trial reveals that Kadcyla (T-DM1) significantly improves overall survival in HER2-positive early breast cancer patients with residual invasive disease. • The study demonstrated a 7-year overall survival rate of 89.1% with T-DM1 compared to 84.4% with trastuzumab monotherapy, indicating a substantial survival advantage. • Kadcyla also showed a sustained improvement in invasive disease-free survival, with a 7-year rate of 80.8% versus 67.1% for trastuzumab, reinforcing its efficacy. • The safety profile of T-DM1 was acceptable, with manageable adverse events, further supporting its use in the adjuvant treatment of high-risk early breast cancer.last yearHER2-Targeted Therapies Solidify Role in Early-Stage HER2-Positive Breast Cancer Treatment• Neoadjuvant HER2-targeted therapy, including trastuzumab and pertuzumab, has become a standard of care for stage II/III HER2-positive breast cancer, improving event-free and overall survival. • The NeoSphere trial established pathologic complete response (pCR) as a primary endpoint for neoadjuvant drug approval, demonstrating the efficacy of docetaxel, trastuzumab, and pertuzumab. • The KATHERINE trial demonstrated that ado-trastuzumab emtansine (T-DM1) improves disease-free and overall survival in patients with residual invasive disease after neoadjuvant HER2-targeted therapy. • Subcutaneous trastuzumab and pertuzumab offer similar efficacy to IV formulations, with patient preference leaning towards the subcutaneous option due to convenience.last year
